Hi can anyone help?, im at the end of the second level, I have killed the big fire monster in the pool, and am in a room with 3 chambers to the left and one to the right, ive killed all the monsters, and have placed all 3 heads in the holes in the walls at the back of the chambers, however only the first head did anything, (opened the door to a chamber on the other side), in which there seems to be another door wich i presume should be opened by the other heads?, why isnt it working!!!!, what am i missing!!! help!!!

don't think at this stage you have all the powers (ice, fire, electricity) so you're just looking to get the next piece of talisman. If there are areas to fire stones at above the doors then fire ice for blue, fire for red.But if i remember right the talisman is in the room on the right - then you move on to next part of game.
